check the 4 pin ribbon from the laser
sounds like it may not be connecting
I MADE PROGRESS!!! It wasn´t the 4pin laser ribbon, I checked it with a dead unit - focus worked. And it also worked on the new laser.
Now, a short overview what I did so far:
-changed Laser
-relubed Gears
-changed out broken Gear with Chop´s Gear
-Replaced 7805
-Replaced BA6290A
-complete Cap replacement
-resoldered the burned connection below the SCSI plastic connector (the one that fits into the IFU)
-re-adjusted pots again TODAY to recommended values
Drive now finds TOC!
Only downside: >>>>> SLED DOESN´T MOVE AT ALL <<<<<<<
>>>>> LASER ONLY FOCUSES AFTER I TIP IT TO CENTER SWITCH! <<<<<<
Both problems are connected to each other - if sled doesn´t move to center, no focus/CD check.
So do I have a dead sled motor?
Or is it the movement circuit?
Where would I have to look for a dead solder joint considering the sled circuit?
I think I AM VERY CLOSE, since the Drive is finding the TOC, and when I move the pots I can hear that it is going to react to it like everybody else described, so I think the relevant parts must be still functional.
Anybody with a hint perhaps?
